阿勒泰地区雾的气候特征与变化趋势及其对人体的影响研究

Characteristic and Changing Trends of Fog in Altay Region and Its Influence on Human Body

利用1961年-2012年阿勒泰地区气象观测资料,对雾的时空分布特征和变化趋势进行分析。结果表明:阿勒泰地区雾日数在时间分布上,初春的3月出现最多;冬季(12月-翌年2月)雾出现的比例最高,占37.6%。20世纪80年代年雾出现日数最多,2000年至今最少。阿勒泰地区雾日数在空间分布上也不是很均匀,区域性为西部的吉木乃、哈巴河县最多,东部的富蕴、青河县最少。阿勒泰地区雾出现日数年变化率与各县站的变化趋势一致,均呈明显的下降趋势,在1966年出现了减少的突变现象。R/S方法分析表明,各县站未来的年雾出现日数仍会呈减少趋势,雾天对人体有一定的影响。

Based on meteorological observations in Ahay region during 1961 -2012, this paper analyzed the temporal and spatial distribution characteristics and changing trends of fog. Results show that March or early spring recorded the most fog days ; in winter（ Decembr to February of the following year）witnessed 37.6% of fog days, the highest proportion in all year aroud. The 1980s recorded most days and since 2000 to present recoded the least number of fog days. Fog days in Altay region is uneven in spatial distribution. Jeminay, Habahe County in Western areas recorded most fog days, while Fuyun and Qinghe County in the East recoded the least fog days. The annual changing rate of fog days Altay region is consistent with the trends of various county monitoring stations, showing a clear downtrend. The year of 1966 saw a reduction of fog incidences. R/S analysis shows that the number of fog days will decrease in the future and fog had influences on the human body.
